In the 1980s, Fleetguard® took another step forward with the introduction of combination full flow/by-pass filtration in the patented LF3000™. The LF3000™ led the way for today's advanced lube filtration systems, which provide increased engine life over all service intervals, as well as:

	Extended service intervals
	Increased vehicle uptime
	Decreased vehicle maintenance costs
	Reduced disposal costs

Why By-pass Filtration Is Superior
With the introduction of combination lube filtration technology, Fleetguard® revolutionized the industry. As SAE 710813/790098 confirms, by-pass filtration reduces engine wear in the following key areas:

	Upper connecting rod bearing shell
	Lower connecting rod bearing shell
	Upper main bearing shell
	Lower main bearing shell

StrataPore™ Media
By implementing the revolutionary StrataPore™ multi-layered media in the 1990s, the combo filter was improved even more. StrataPore™ was introduced in the full flow section to work in combination with the stacked discs to remove the smallest dirt particles, which cause the most engine damage. This configuration reduces engine wear by as much as 60% in some applications.

Venturi™ Combo System
The technology was taken even further with the introduction of the Venturi™ Combo. The OEM-approved Venturi™ allows the lube system to perform up to four times as long and remove up to three times the contaminants as a full synthetic filter. The patented Venturi™ nozzle provides a low-pressure zone for the oil to flow through the pleated media for increased efficiency. This innovative technology results in longer life and better performance for your vehicle. And, unlike its competitors, the Venturi™ Combo was tested in a real world environment, not bench tested.
